TH502EX - Porous iron processing - Google Patents

Abstract

In the processing of porous ores containing iron, especially porous iron, this is a process that will prevent repeated oxidation and / or corrosion that can occur during storage. Maintain and transport Proposed to grind porous iron ore tablets in lime powder. Then moisten the above mineral tablets with normal water in the amount Less than necessary for hydration to fully absorb the water. Stearate, oleylate, paraphene, fat, soap or waste material containing added fats and soaps. With lime powder Suggested that the anti-water additives should be added With the water to use to soak the lime However, the impurities mentioned above Must also be a water-soluble compound. For example, ammonium satiate, mixing water-resistant additives with lime or oxide powder. Of iron, it will do the same. This process may act in a manner That creates a double coating of porous iron In this case there will be Only add a water repellent impurity in the second coating layer.

1. Process for processing iron ore tablets In particular, porous iron is used to prevent repeated oxidation and / or decay that would occur during storage and transportation. Obtained from sintering and involved in the production of porous steel Then do The above mineral tablets are moistened with a smaller amount of water than the Required to make lime fully absorb water. Specifically, the use of water-repellent impurities, such as stearate, oleylate, paraphene, fat, soap and
